I've just formatted my sister's presario c700 with Windows 7 Ultimate x64. I didn't know how to access the webcam. In WinXP, you just double-click the webcam at My Computer. You can use the webcam without any driver and without any 3rd party software. Do you know how to access webcam in Win7 without installing anything? I've googled it and most of the result shows that they have to install driver blah blah blah... but i know that the webcam is ready and doesn't 3rd party driver. Can you help me?
